项目摘要

This project addresses a fundamental question in plant biology, how plants deal with environmental stresses, by comparing differing ecological habitats of Hawaii and Mexico. The research focuses on the ecology and physiology of prickly poppy, genus Argemone, which is found in both regions. The project leverages complementary expertise between U.S. and Mexican researchers and provides unique training opportunities to U.S. students from underrepresented groups. U.S. students and researchers will travel to Mexico to join an international collaborative team and gain experience in plant functional trait analysis, herbarium research, and preliminary field data collection. While most defense traits in plants are multi-functional the majority of studies have examined one or few plant traits at a time. Prickly poppies display a suite of functional traits (e.g. prickles, latex exudation, tough leaves) that make them a compelling case study for this research. This broad approach to investigate multiple plant traits and their multi-functionality within an ontogenetic context will provide a more holistic understanding of how plants deal with environmental stresses. Furthermore this research will uncover synergies, redundancies and developmental constraints in plant functional traits and thereby further understanding of plant biology.

该项目通过比较夏威夷和墨西哥的不同生态栖息地来解决植物生物学的一个基本问题，即植物如何应对环境压力。该研究的重点是在两个地区都发现的刺激罂粟的生态和生理学。该项目利用美国和墨西哥研究人员之间的互补专业知识，并为来自代表性不足的团体的美国学生提供了独特的培训机会。美国的学生和研究人员将前往墨西哥加入国际合作团队，并获得植物功能性状分析，植物标本室研究和初步现场数据收集方面的经验。尽管植物中的大多数防御性状都是多功能的，但大多数研究一次都检查了一个或几种植物特征。刺罂粟展示了一套功能性状（例如刺，乳胶渗出，坚硬的叶子），使它们成为这项研究的引人注目的案例研究。在本体发育环境中研究多种植物特征及其多功能性的这种广泛方法将为植物如何处理环境压力提供更全面的理解。此外，这项研究将揭示植物功能性状的协同作用，冗余和发育约束，从而进一步了解植物生物学。
